After the establishment of the First Czechoslovak Republic the housing for the socially disadvantaged population became a complex problem, especially for the cities with a lot of industry and therefore a large population. Grim living conditions in the cities were a trend even before 1914. After the First World War, however, the housing crisis peaked. Some marginalized groups had no housing available or lived in a totally unsuitable environment. State authorities tried to resolve the housing crisis via numerous legislative measures.
